Renewables: Why The Reluctance?

Despite the world's growing demand for energy, people are not investing more in renewable energy due to various reasons. One of the main obstacles is the cost of renewable energy technology, which can be expensive to build and install. Additionally, renewable energy sources face competition from established fossil fuel industries that benefit from existing infrastructure and policy support. There is also a lack of education about renewable energy, which leads to lower adoption rates. Other barriers include the geographic limitations of renewable energy sources and the reliability of fossil fuels. However, investments in renewable energy have been increasing, and some countries, like China, the United States, and Japan, are leading the way in this transition.

High upfront costs

Investing in renewable energy technologies involves high upfront costs, which can vary depending on the type, scale, and location of the project. For example, installing solar panels in urban areas will likely differ in cost from setting up a solar farm in an offshore environment. These upfront costs are often the most significant barrier to renewable energy adoption.

The bulk of the expense comes from building the technology, as most renewable energy sources are exceedingly cheap to operate, with minimal maintenance and no fuel costs. However, the initial investment in renewable energy projects can be substantial, including costs for project assessment, equipment purchases, and construction. For instance, the average cost of installing solar systems in 2017 ranged from over $2,000 per kilowatt for large-scale systems to almost $3,7000 for residential systems.

These high upfront costs can pose challenges for project developers and end users, who may not have sufficient cash on hand to fund the initial installation. As a result, they may need to seek financing through bonds, loans, leases, or power purchase agreements to spread the costs over multiple years.

The high upfront costs of renewable energy projects can also make them seem riskier to financial institutions, leading to higher lending rates and making it more difficult for utilities or developers to justify the investment. This is especially true when compared to fossil fuel power plants, where fuel costs can be passed on to consumers, lowering the risk associated with the initial investment.

However, it is important to consider the total costs over the lifespan of these energy projects. According to asset management company Lazard, wind and utility-scale solar can be the least expensive energy-generating sources when considering long-term costs. Additionally, renewable energy capital costs have been decreasing over time and are expected to continue doing so.

Fossil fuels are more reliable

Renewable energy sources, such as solar and wind power, are intermittent and dependent on weather patterns. For example, solar panels cannot generate power after sundown and become less effective when it is overcast. Wind turbines cannot make electricity if the wind speed is too low or too high.

The ease of installing power plants is another factor that makes fossil fuels more reliable. Fossil fuel power plants can be easily set up in almost any location, even remote ones, whereas alternative energy sources require natural features like rivers, oceans, abundant sunlight, or steady wind.

The abundance of fossil fuel sources also contributes to their reliability. Coal and natural gas are found in many places around the world, and most countries can extract some type of fossil fuel within their borders. In contrast, alternative fuels, such as those made from biomass, require abundant farmland, which not all countries have.

Furthermore, fossil fuels are currently widely available due to decades of use. Mines, equipment, and reserves are easy to find, and the technology for working with them is low-cost. This gives countries at different levels of affluence access to this energy source.

While renewable energy sources are becoming more affordable and competitive, fossil fuels remain more reliable in terms of their widespread availability, well-established infrastructure, and lack of dependence on weather conditions.

Lack of education about renewable energy

The lack of education about renewable energy is a significant barrier to its wider adoption. People are less likely to use renewable energy sources if they are unaware of their existence or their benefits. This lack of awareness is particularly pronounced in secondary school education, which is crucial for instilling awareness and motivation to pursue further education and careers in renewable energy.

The negative dissemination of renewable energy technologies, design, and concepts is often due to the lack of education in this field during the secondary education years. This results in socio-cultural, institutional, and technological barriers that hinder the adoption of renewable energy.

The high cost of implementing renewable energy technologies is also a factor, as people may not understand the long-term benefits and return on investment. Additionally, there is a lack of creative methods for harnessing renewable energy sources, and some existing technologies cannot fully meet energy demands, making them less cost-effective.

Implementing renewable energy education at the secondary school level and providing realistic laboratories and natural environments for teaching and learning can help address these issues. Increasing public awareness through media campaigns and training sessions is also crucial to ensure a basic understanding of renewable energy and its benefits among citizens.

Furthermore, renewable energy education can empower individuals to make informed choices about their energy consumption and adopt more sustainable practices. It can also drive innovation and create a skilled workforce capable of developing, maintaining, and innovating renewable energy technologies.

Overall, a combination of education and financial development policies is necessary to promote the adoption of renewable energy effectively.

Fossil fuels are well-established

The infrastructure for fossil fuels is already in place, and the transition to renewable energy sources will require significant time and investment. Fossil fuels are also cheaper to fund than renewable energy sources, and the cost of fuel can be passed onto the consumer, making them more attractive to investors.

The fossil fuel industry is heavily integrated into the global economy and has been the backbone of human development. The burning of fossil fuels has enabled us to generate electricity, run vehicles, and power machinery. Fossil fuels have also been used to create derivatives such as kerosene, gasoline, and diesel, as well as products like plastics and paint.

The established nature of the fossil fuel industry presents a significant barrier for renewable energy sources to overcome. Fossil fuels have existing infrastructure, expertise, and policies in their favour, making it a challenging market for new technologies to enter. The wealth and influence of the fossil fuel industry further contribute to this challenge, as they have historically spread misinformation about climate change and continue to lobby for favourable policies and subsidies.

Despite the drawbacks of fossil fuels, including their environmental and health impacts, they remain a well-established and integral part of our energy landscape.

Renewable energy has geographic limitations

Renewable energy sources have geographic limitations. For example, wind energy can only be harnessed in areas that get a lot of wind, and wind farms are most often seen on the tops of hills or offshore. Similarly, hydroelectric dams and wave turbines can only be built in specific areas. Solar panels can be installed in more locations, but they require direct sunlight to be effective. This means that certain areas, such as those with frequent cloud cover or shade, are not suitable for solar energy generation.

The availability of renewable energy sources can also vary depending on weather conditions. For instance, wind and solar energy production may be affected by inconsistent wind speeds or a lack of sunlight on cloudy or rainy days. This variability can make it challenging to rely solely on renewable energy sources in some geographic regions.

In addition, the selection of appropriate sites for renewable energy projects can be challenging. Siting, or finding suitable locations for wind turbines, solar farms, and other infrastructure, requires negotiations, contracts, permits, and community relations. These factors can increase costs and cause delays or even cancellations of projects.

Furthermore, the transmission of electricity from renewable energy sources to where it is consumed can be another geographic limitation. The existing infrastructure, such as power lines and grids, may not be adequately located or designed to accommodate renewable energy sources, requiring additional investments in transmission infrastructure.

Overall, while renewable energy sources offer many benefits, their geographic limitations are an important consideration when deciding whether to adopt them.
